Two Brothers Racing, continually dedicated to Top Level Performance, dials in Fuel Injection performance like never before with the Juice Box Pro. Offering memory capacity for up to 10 fully custom fuel maps and virtually limitless tuning potential, the Juice Box Pro revolutionizes the plug-and-tune category of performance electronics

Custom-Designed Fuel Mapping

Juice Box Pro is the only fuel management interface to offer preloaded, dyno tested bike-specific mapping and the ability to fully customize and build your own Power Maps via computer in a simple to- install, user-friendly component

Through TBR’s Direct Injector Control, the fuel circuits on current sport bikes can be modified both richer and leaner than stock as much as -100% to 250% in any particular area of the power spread with the Juice Box Pro. Also, up to 10 pre-programmed TBR Power Maps (custom made and dyno tested for each Two Brothers Racing exhaust system) are adjustable to your preference

Riders can literally select between a TBR Power Map, custom-built maps, or even fine tune low, mid or high rpm ranges while sitting on the bike and without plugging in to a computer. Standard /- 10% increments from selected map settings, different ranges are available using the supplied Top Tune software

Computing Power

For racers and riders looking for the ultimate in precise adjustment and fuel map customization and creation, Two Brothers Racing’s Top Tune software allows PC-based Power Map creation at 250-rpm increments and 10 different throttle positions. Modification parameters vary upon make and model of machine and fuel changes made in these increments are automatically interpolated between the rpm and throttle position ranges ensuring a smooth final power curve

Users can load up to 10 of their personally built Power Maps into the Juice Box Pro and select between them while in the saddle— eliminating the need to “re-boot” with the computer every time a new map is desired
